What considerations should be made when transferring a user list from an old website to a completely new one in PHP?

When transferring a user list from an old website to a completely new one in PHP, considerations should be made to ensure that the data is securely migrated and that any necessary data transformations or validations are applied during the transfer process.

php 
// Example code snippet for transferring user list from old website to new website in PHP

// 1. Connect to the old website's database
$old_db = new mysqli('old_website_host', 'old_website_username', 'old_website_password', 'old_website_db');

// 2. Connect to the new website's database
$new_db = new mysqli('new_website_host', 'new_website_username', 'new_website_password', 'new_website_db');

// 3. Query the user list from the old website's database
$old_users = $old_db->query('SELECT * FROM users');

// 4. Loop through the old user list and insert each user into the new website's database
while ($user = $old_users->fetch_assoc()) {
    // Apply any necessary data transformations or validations here
    $new_db->query("INSERT INTO users (username, email, password) VALUES ('{$user['username']}', '{$user['email']}', '{$user['password']}')");
}

// 5. Close the database connections
$old_db->close();
$new_db->close();
